Pictured above is a screen capture showing a new (late July 2017) feature of GPIOZero for the Raspberry Pi – pinout – which shows the status of the general purpose input/output pins of the Raspberry Pi and additional useful information about your Pi.
Simply enter pinout at the command prompt. If the command is not recognised, do a sudo apt-get update; sudo apt-get upgrade to update your Raspberry Pi and GPIOZero software to the latest version, and it will then work.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
